First there is this is from the Wix Documentation http://wix.sourceforge.net/manual-wix3/major_upgrade.htm And then there is this from the excellent Wix Tutorial http://wix.tramontana.co.hu/tutorial/upgrades-and-modularization Beyond that, if you have a more specific question I am sure someone will be able to answer it.
